Friction welded filter housing

Abstract

A method to provide a sealingly bonded filter housing comprises the steps of bonding a first end member to a first end of a body portion, forming an aperture in said body portion, and bonding a second end member to a second end of the body portion, to provide a sealingly bonded filter housing.

We claim: 
     
       1. A method of making a filter housing comprising, in the following sequence, the steps of first friction welding a cylindrical body portion to a first end member,   then providing an aperture in said body portion,   thereafter friction welding a second end member to the other end of the cylindrical body portion,   attaching an inlet adapter to the cylindrical body portion in communication with said aperture,   and finally providing threaded bores in the second end member mounting thereof.
